Not entirely. A vessel will float provided its displaced weight is such that there is ample freeboard remaining. If there is no freeboard, there will be nothing to prevent the water from coming inboard and sinking the vessel. On a small boat, buoyancy bags will prevent the boat from sinking to the bottom of the sea, even if filled with water.

Buoyancy is just a short-hand for that.

The upward force of a liquid or air on an object that helps it float?
The force that makes things float is called buoyancy.
What does the statement 'the buoyant force of a liquid does not depend on physical statebut on density' mean?
Floating, or buoyancy, depends on the density of the liquid and the density of the object. Water is a pretty dense liquid, and things float in it; they are buoyant. Oil or gasoline are less dense; things that float in water may not float in oil.
Why a cork float in a salt water?
The salt in the water causes everything to have more buoyancy (Meaning it makes things more likely to float.) If you die in the ocean your body is more than likely going to float unless it is attached to something heavier is attached.
The contact force that acts on objects in a liquid or gas and allows objects to float is called density or buoyancy?
buoyant force
What makes things float in water?
Buoyancy force is what causes things to float in water. To calculate buoyancy, use Archimedes' Principle: the buoyancy force of a submerged (or partially submerged) object is the weight of the volume of water that the object displaces. In other words, find the volume of the object that is under water, and multiply that by the density of water (1000 kg/cubic meter) and gravity (9.8 meter/sec/sec). It is also density that makes things float in water. If the object has less density than water, it will float.
Why does bouyancy lift things in water?
Buoyancy is an upward lifting force, which means in the water buoyancy can make things float, for example: a rubber duck, pineapple, softball, etc. And that of buoyancy can make you float in the water.
Why do things float but not others?
because of buoyancy!
The upward force of a liquid or air on an object that helps it float?
The force that makes things float is called buoyancy.
What is he name of the force that helps things float?
Buoyancy
Which property of water allows things to float?
There is NO property of water that allows things to float. Floating in not a property of a substance. It is the difference in density of two objects that allows one to be buoyant when surrounded by the other. This a balloon can float on air, A steel ship can float on water and oil can float on water.
What forces make things float?
Gravity. When you place something on a liquid, and it is less dense than the liquid, gravity pulling down on the liquid forces the object to float.
What makes some things float?
Density of the object and buoyancy of the water/liquid.
What does buoyancy help with?
High buoyancy=easy to float
What is buoyancy and how is it affected by density?
Buoyancy is the factor of things that float or sink. Density is related because if the object has more density than water, it will sink. But, if it has less density than water, the object will float.
Can you make objects that are sinkers float?
It depends on the buoyancy of an object in relation to the liquid it is in.
How does buoyancy float?
Buoancy is the upward force that keeps things floating. I guess it doesn't need surface tension.. http://en.wikipedia.org/wiki/Buoyancy
How does an objects size and shape affect buoyancy?
Well, buoyancy is capacity to float in liquid. So the object needs to have air to make it float an example for an boat the Titanic for example was really heavy it was made out of steel so it had air in the bottom to make the ship float.
